Ovarian endometrioma is a common form of endometriosis, which may cause infertility, dysmenorrhea and pelvic pain in women of reproductive age. Although surgery is the treatment of choice for endometriomas, recurrence poses a formidable frustration. This study investigated potential risk factors of endometriomas recurrence, aiming to better understand its pathogenesis. A total of 307 patients with endometriomas were followed up for an average of 28.6 months and the 1-, 2- and 3-year cumulative recurrence rate was 9.5%, 21.9%, and 29.2%, respectively. Twenty-one potential risk factors for endometriomas recurrence were evaluated using Cox's proportional hazards models. Total revised American Fertility Society (rAFS) score was significantly associated with higher recurrence (OR=1.858, 95% CI=1.122-3.075, P=0.016), as well as younger age at surgery (OR=0.953, 95% CI=0.915-0.992, P=0.020). Semiradical surgical treatment was defined as surgical removal of cyst plus hysterectomy with preservation of bilateral or unilateral ovary, and was a significant factor that was associated with lower recurrence than the conservative surgery (OR=0.318, 95% CI=0.107-0.951, P=0.040). Postoperative pregnancy was favorable factors for disease recurrence (OR=0.217, 95% CI=0.102-0.460, P=0.000). The results suggest that endometrioma recurrence is inversely associated with age at surgery and postoperative pregnancy, and may correlate with total rAFS score and conservative surgery method.

Linezolid is the first oxazolidinone antibacterial drug approved by the FDA, which can effectively treat various gram-positive bacterial infections, including blood infections, skin and soft tissue infections, community and hospital-acquired pneumonia. It has become one of the most commonly used antibiotics in clinical. In addition to the recently launched tedizolid phosphate (TR701) and contezolid (MRX-I), several oxazolidinone anti-infective candidates are currently under clinical research. This review briefly introduces the oxazolidinone antibiotics that have been marketed and are in clinical trials, and recent progress on the structure optimization of oxazolidinone drugs is also summarized.

OBJECTIVETo assess the association between single nucleotide polymorphisms (SNPs) of forkhead box P3 gene (FOXP3) and endometriosis in Chinese Han women from central China.

METHODSMassARRAY IPLEX and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) technique was used to determine the genotypes of FOXP3 gene in 314 patients with endometriosis and 358 healthy controls.

RESULTSGenotypes of C/T polymorphism for the rs2280883 locus, A/C for the rs3761548 locus, and C/T for the rs3761549 locus were determined. No significant difference was detected in distribution of genotypes CC, CT and TT (P=0.770, OR=0.960; P=0.923, OR=1.013) and frequencies of C and T alleles (P=0.772, OR=0.960; P=0.925, OR=1.013) for rs2280883 and rs3761549 between the two groups. And no significant difference was detected in distribution of genotypes AA, AC and CC (P=0.762, OR=0.958) and frequencies of A and C alleles (P=0.715, OR=0.950) for rs3761548 was detected between the two groups. Based on r-AFS classification, the patients were divided into two groups (respectively with I-II stage and III-IV stage endometriosis). Again, no significant difference was detected in distribution of genotypes CC, CT and TT (P=0.454, OR=1.198, P=0.526, OR=0.909; P=0.220, OR=0.750, P=0.548, OR=1.094) and frequencies of C and T alleles (P=0.473, OR=1.215, P=0.532, OR=0.912; P=0.204, OR=0.737, P=0.558, OR=1.089) for rs22080883 and rs3761549 loci between the two patient groups. No association was found between distribution of genotypes AA, AC and CC (P=0.431, OR=1.211; P=0.508, OR=0.905) and frequencies of A and C alleles (P=0.417, OR=1.226; P=0.516, OR=0.908) for rs3761548 locus between the two patient groups.

CONCLUSIONOur study has failed to found any association between FOXP3 gene polymorphisms rs2280883, rs3761548 and rs3761549 with endometriosis in Chinese Han patients.

BACKGROUNDIn recent years, the incidence of unexplained sudden death has risen significantly across the world. However, it occurred suddenly, often in young apparently healthy individuals and almost 50% of the patients did not have any warning signals or symptoms. Therefore, the prodromal symptoms before the incident are extremely important for early prediction of sudden death. In this article, we aimed to explore the value of prodromal symptoms for unexplained sudden death and whether the prodromal symptoms have a predictive function to unexplained sudden death (USD) without underlying diseases.

METHODSA total of 208 sudden death cases were selected for the survey in the Emergency Department of Peking University Third Hospital from January 2006 to December 2009 and their medical records were reviewed. The patients were divided into two groups, 65 patients had underlying diseases while 143 had not underlying diseases. In the meantime, their prodromal symptoms were collected and compared, prodromal symptoms including chest distress, dyspnea, syncope, fever, headache, vomiting, etc.

RESULTSPatients with underlying diseases were compared to those without underlying diseases associated with sudden death; there was no significant difference in gender and age distribution. Among the 208 cases, 39 cases (18.75%) had prodromal symptoms, patients with underlying diseases had prodromal symptoms in 12 cases (18.46%), while patients without underlying diseases had prodromal symptoms in 27 cases (18.88%). The difference between the two groups with prodromal symptoms was not statistically significant (P > 0.05).

CONCLUSIONSProdromal symptoms are extremely important warning signals in the occurrence of USD. It has equally important predictive value for patients both with and without underlying diseases, especially in predicting sudden death caused by cardiopulmonary and neurological diseases.

To investigate the influence of such individual factors as gender, age and tissues in vitro to the postmortem interval (PMI) by the Fourier transform infrared (FTIR) spectrometer in animal experiments. SD rats were classified into male and female groups, different age groups (21-day, 42-day and 63-day group), and tissues in vitro and in vivo groups. The rats were sacrificed by cervical dislocation, whose bodies were kept in a controlled environmental chamber set at (20+/-2) degrees C and 50% humidity. The liver, kidney, spleen, myocardium, brain, lung and skeletal muscle tissues were collected for measurement from time zero to 48 h postmortem. With the change of PMI, no obvious changes were found in the main FTIR absorbance peaks and their ratios at different time points. All the experimental groups showed no significant changes when compared with the controls. The gender, age and tissues in vitro were not found to be contributing factors in the estimation of PMI via FTIR spectroscopy.

BACKGROUNDHypotension induced by combined spinal epidural anesthesia in parturient with hypertensive disorders of pregnancy (HDP) can easily compromise blood supply to vital organs including uteroplacental perfusion and result in fetal distress. The aim of this study was to investigate whether the goal-directed fluid therapy (GDFT) with LiDCO rapid system can improve well-being of both HDP parturient and their babies.

METHODSFifty-two stable HDP parturient scheduled for elective cesarean delivery were recruited. After loading with 10 ml/kg lactated Ringer's solution (LR), parturient were randomized to the GDFT and control group. In the GDFT group, individualized fluid therapy was guided by increase in stroke volume (ΔSV) provided via LiDCO rapid system. The control group received the routine fluid therapy. The primary endpoints included maternal hypotension and the doses of vasopressors administered prior to fetal delivery. The secondary endpoints included umbilical blood gas abnormalities and neonatal adverse events.

RESULTSThe severity of HDP was similar between two groups. The total LR infusion (P < 0.01) and urine output (P < 0.05) were higher in the GDFT group than in the control group. Following twice fluid challenge tests, the systolic blood pressure, mean blood pressure, cardiac output and SV in the GDFT group were significantly higher, and the heart rate was lower than in the control group. The incidence of maternal hypotension and doses of phenylephrine used prior to fetal delivery were significantly higher in the control group than in the GDFT group (P < 0.01). There were no differences in the Apgar scores between two groups. In the control group, the mean values of pH in umbilical artery/vein were remarkably decreased (P < 0.05), and the incidences of neonatal hypercapnia and hypoxemia were statistically increased (P < 0.05) than in the GDFT group.

CONCLUSIONSDynamic responsiveness guided fluid therapy with the LiDCO rapid system may provide potential benefits to stable HDP parturient and their babies.
